Hilary Duff vs. One Direction – Pop Clash

Update: One Direction won this round of Pop Clash! Now they're facing off against Maroon 5's 'Maps.' Click here to vote.

Once again, Hilary Duff's fans have dominated Pop Clash! The singer's 'All About You' beat out Jennifer Lopez's 'Booty,' claiming 73% of the votes. This week, Hilary faces off against One Direction's 'Steal My Girl.' Which song should win this round of Pop Clash?

We're not afraid to admit that we're totally obsessed with Hilary's 'All About You.' While we came for the infectious folk-rock vibe, we stayed for Hilary's ultra-confident lyrics. (Mile-high club, anyone?) Seriously, what's not to love?

As long as we're talking about music obsessions, we can't leave One Direction's 'Steal My Girl' off the list! The track is a totally different sound for the guys, which we love. It's giving us some serious anthemic-rock vibes. It's a departure from the youthful 'Best Song Ever,' but we're glad to see 1D channel their maturity into their music.

Which song should win this week's Pop Clash? You can vote for Hilary Duff or One Direction once an hour until the polls close at 3PM ET on Oct. 6.
